From @noirlabastro.bsky.social: This image reveals details in the outskirts of the Orion Nebula. The white-blue spots are clouds of gaseous iron ‘bullets’ being propelled at supersonic speeds from a region of massive star formation. #astronomy

📷: International Gemini Observatory/NOIRLab/NSF/AURA
The image shows the Orion "bullets" as blue features and represents the light emitted by hot iron (Fe) gas. The light from the wakes, shown in orange, is from excited hydrogen gas.This image brings into focus a remarkably detailed view of supersonic “bullets” of gas and the wakes created as they pierce through clouds of molecular hydrogen in the famous Orion Nebula. The image was made possible with laser guide star adaptive optics technology that corrects in real-time for image distortions caused by the Earth’s atmosphere.

This week’s image is of Jupiter! Since this image comes from Gemini North NIRI, which has a field of view of 22x22”, a mosaic of multiple images was used to obtain this stunning portrait peering into Jupiter’s cloud-forming region. Check out a few paper highlights in the thread! #Astronomy
An infrared image of the planet Jupiter, showing its atmospheric heat patterns in glowing shades of orange and gold against a black background. The image highlights the planet’s distinct horizontal bands: the darker, cooler cloud decks appear as deep brown or black stripes, while the warmer, deeper layers of the atmosphere glow brightly. A prominent dark oval in the southern hemisphere represents the Great Red Spot, which appears cool in this thermal view. Smaller swirling vortices are visible across the entire surface
